The composition shingles on my 14 year old house need to be replaced. Is it
necessary to remove the old shingles first, or can the new ones be installed
over the old ones?


Thanks

It's possible and a lot are done that way to save some money, but it's a
foolish shortcut imo...

Why would you want to put a costly new material over old, failing
material, causing almost certainly, a shorter lifetime of the new
material you just spent good $$ for? Never make a lick of sense to me,
but it's your roof...

This is Turtle

Yes you can lay over old shingles but most people don't because of weight of
them on the roof and some people in the roofing business say it will damage the
new shingles in someway.

One ideal of this is the next time you recarpet you living room, lay the new
carpet over the old and would you like it done that a way ?

you can have 3 layers of roofing. after this you must do a "tear off",
remove all roofing and start fresh

They say you can put up to 3 layers on a roof but why as another poster
stated!

=================================
14 years indicateds to me that the buiklder sure used the cheapest
shingles available...

Anyhow... My dad (now deceased) ran a roofing company and our own home
was done by not tearing the old shingles off... Dad was NOT
cheap...and not afraid of doing a lot of work... I was only about 8-9
then and I remember his ONLY concern was the additional weight on the
roof... IF I remember correctly the second layer held up for over 20
years before he tore both layes off and installed another roof...

When a roofing contractor does not bother to rip off the 1st layer on
his own home.... I honestly have to say it is not needed...

It depends a lot on the condition of the underlying layer...I personally
still think it a false economy.
